Given AP : - 11, - 8, - 5...........49
To find 4th term from end let us reverse the AP
Therefore
AP : 49.........-5, - 8, - 11
let a be the first term and d be the common difference....
Here a = 49........d= - 3
an = a + (n-1)d
a4 = 49 + (4-1) - 3
= 49 + 3 * - 3
= 49 - 9
= 40✔️✔️
Therefore 4th term from last is 40
Pls mark it brainliest....
